Your .skp files open as they are
Components, groups, tags, materials and textures, each in its place, from files more than ten years old or from this very year. And when you're done, you can save them back as .skp.
It also opens DWG, DXF, IFC, OBJ, STL, glTF, COLLADA, FBX, 3DS, KMZ, USDZ and point clouds.
See all formatsYour shortcuts, the usual ones
L for line, R for rectangle, P to push. The tools are where you expect them and answer to the keys you already have in your fingers: on day one you're already modeling.
